Charley Colms (1912)

Early in his crime-solving career, Sherlock Holmes attempts to prevent Moriarty from cornering the heroin market.

After spending decades living in the shadow of his more famous and successful sibling, Consulting Detective Sigerson Holmes is called upon to help solve a crucial case that leads him on a hilarious trail of false identities, stolen documents, secret codes... and exposed backsides.

Sherlock Holmes is drawn into the case of Jack the Ripper, who is killing prostitutes in London's East End. Assisted by Dr. Watson, and using information provided by a renowned psychic, Robert Lees, Holmes finds that the murders may have their roots in a Royal indiscretion and that a cover-up is being managed by politicians at the highest level, all of whom happen to be Masons.

When Watson reads from the newspaper there have been two similar murders near Whitechapel in a few days, Sherlock Holmes' sharp deductive is immediately stimulated to start its merciless method of elimination after observation of every apparently meaningless detail. He guesses right the victims must be street whores, and doesn't need long to work his way trough a pawn shop, an aristocratic family's stately home, a hospital and of course the potential suspects and (even unknowing) witnesses who are the cast of the gradually unraveled story of the murderer and his motive.

In 1947, long-retired and near the end of his life, Sherlock Holmes grapples with an unreliable memory and must rely on his housekeeper's son as he revisits the still-unsolved case that led to his retirement.

During WWII several murders occur at a convalescent home where Dr. Watson has volunteered his services. He summons Holmes for help and the master detective proceeds to solve the crime from a long list of suspects including the owners of the home, the staff and the patients recovering there.

May Munro is a woman obsessed with getting revenge on the people who murdered her parents when she was still a girl. She hires Ray Quick, a retired explosives expert, to kill her parents' killers. When Ned Trent, embittered ex-partner of Quick's, is assigned to protect one of Quick's potential victims, a deadly game of cat and mouse ensues.

Now a detective-for-hire like her infamous brother, Enola Holmes takes on her first official case to find a missing girl, as the sparks of a dangerous conspiracy ignite a mystery that requires the help of friends — and Sherlock himself — to unravel.

Detective Hazel Micallef hasn't had much to worry about in the sleepy town of Port Dundas until a string of gruesome murders in the surrounding countryside brings her face to face with a serial killer driven by a higher calling.

During a murder hunt game at a country house, to which Hercule Poirot is invited as an "expert", a real murder occurs.
